Inliner, Blindenmarkt (Austria)

Austria

This project was for a 1700 m long subsection of the 4.3 km long Hubertendorf – Blindenmarkt section of a major upgrade to Austria's main east-west railway line. This 1700 m subsection was built using the 'top-cover' underground construction method. Because the walls were braced against one another by the tunnel formwork traveller, there was no need to use any expendable anchoring components for casting the inliner (single-sided wall).
